Hybrid amorphous-crystalline silicate composites as feasible solid-state electrolytes

Solid-state electrolytes (SSEs) are considered as the most promising materials for enabling safer, more efficient, and feasible solution to address market demands lithium-ion batteries. The current work investigates production of inorganic SSEs from silicate minerals, which abundant in natural resources (kaolinite) well industrial waste-streams (amorphous silica). synthesized showed high amorphous contents combined with lithium phases at variable proportions, according molar proportions reacting system. have been characterized XRD, SEM/EDS, FTIR, TGA-DSC, XPS, EIS, density measurements. results that hybrid structures crystalline silicates can form an ordered hotchpotch morphology. best presented ionic conductivity values 1.42 × 10-4 1.30 Scm−1 samples total 73 83 wt%, respectively. connected structure between a is hypothesized assist hopping Li+ ions via mechanisms segmental motion chains defects phases. proposed approach may offer new research paths towards low-cost scalable SSEs.
